3.
Raise
the
vehicle
by rotating
the
wheel wrench
to
the right (clockwise). Raise the vehicle far enough
off the ground so there is enough room for the spare
tire to fit. Remove all the wheel nuts and take off
the flat tire.
4. Remove any rust or dirt
from the wheel bolts,
mounting surfaces and
spare wheel.
A
CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after a time. The wheel could come
off and cause an accident. When you change a
wheel, remove any rust or dirt from the places
where the wheel attaches to the vehicle. In an
emergency, you can use a cloth or a paper towel
to do this; but be sure
to
use a scraper or wire
brush later, if you need to,
to
get all the rust or
dirt off.
